摘要:

厚板板形是衡量厚板产品质量的重要指标之一,生产中最终板形的及时预报对于调整厚板生产操作与控制具有重要的意义。实际工业生产中,厚板数据具有耦合信息多、冗余信息量大、数据呈现多源异构性等特点,结合厚板板形预报的需求,设计并开发了厚板板形预报系统。利用数据转存功能,对工业大数据进行数据过滤和数据预处理,去除数据中的耦合信息和冗余变量。利用LSTM神经网络、卷积神经网络以及3D卷积神经网络对不同维度的数据分别提取数据特征,基于最大互信息系数将特征进行融合建立集成学习预报模型,有效地解决了多源异构数据所带来的建模困难。采用国内某厚板生产线的实际工业数据进行验证,结果证明了所开发系统的有效性。

Abstract:

Thick plate shape is one of the important indicators to measure the quality of thick plate products.The timely prediction of the final plate shape in production is of great significance for adjusting the operation and control of thick plate production.In actual industrial production, thick plate data has many characteristics, such as multiple coupling information, large amount of redundant information, and multi-source heterogeneity of data.Combining the needs of thick plate shape prediction, a thick plate shape prediction system was designed and developed.The data dump function was used to filter and preprocess the industrial big data to remove the coupling information and redundant variables in the data.LSTM neural network, convolutional neural network and 3D convolutional neural network were used to extract data features from data of different dimensions, and the features were fused based on the maximum mutual information coefficient to establish an integrated learning prediction model, which effectively solved the modeling difficulties caused by multi-source heterogeneous data.The actual industrial data of a domestic thick plate production line was used for verification, and the results showed the effectiveness of the developed system.

Key words: thick plate shape, prediction model, multi-source heterogeneous data, system development
